Will of the Mage: Your hit point maximum increases by an amount equal to your character level when you gain this feat. Whenever you gain a level thereafter, your hit point maximum increases by an additional 1 hit point. In addition, you can cast the Mage Armor spell at will. 

Stage 1 - Cantrip Metamorph: When you cast a leveled spell or cantrip but before you hit a creature or the spells effects activate, you can spend a charge to add the effects and damage of one cantrip you know to the spell. You can do this a number of times equal to your proficiency modifier per long rest. 

Stage 2 - Spell Metamorph: When you cast a leveled spell but before you hit a creature or the spells effects activate, you can spend a charge and spend another spell slot to add the effects and damage of another spell you have prepared to the spell. You do this twice per long rest.
